[Dovecot] dovecot-shared

[Frank Cusack]

I'm confused about dovecot-shared.

If the file exists, \SEEN flags are NOT shared?

So if dovecot-shared exists, flags are actually private.  The doc
seems clear on this (albeit not worded very well).  I only question it
because intuitively you would think the opposite.  If backwards
compatibility is the reason for this reverse behavior, the file should
have been named dovecot-private-flags.  In fact that's a great name
to stick a list of flags (one-per-line) that are private.
